There is an ongoing issue with the G403 that has quite a number of issues , at least not locally as far as we know.  Issues such as lens rattling , LMB/RMB doesn't feel the same. Lens rattling speaks for itself , just hold you mouse in the air and shake it , you will hear rattling noises seemingly from the lens itself.  Most hardcore mouse enthusiasts will find it annoying , I know I do too , in extreme cases it might even affect the tracking of the mouse.

Lens issue was supposedly "fixed" when one of the Logitech G product manager said to have halted production of it until it gets fixed , but still we have plenty of people getting the same issue lol , maybe from the lots of previous stockpile.

Fun fact , the recent Logitech gaming mouse has one or two of the similar issues. The good old days when we used to think Logitech as a long lasting quality product has been long gone now.

so G403 still have rattling issue? i thought of buying one when they arrived here but read the issue i have hold off until now 

Hmmm, why not consider going straight for Logitech G900?

Lately, most electronic gadgets don't last long. I would grateful if all my peripherals last more than 3 years.
